A.T. Robertson Commentary Mark 15:40

"And there were also women beholding from afar: among whom [were] both Mary Magdalene, and Mary the mother of James the less and of Joses, and Salome;" — Mark 15:40 (ASV)

And Salome (κα Σαλωμη). Apparently the "mother of the sons of Zebedee" (Matthew 27:56). Only in Mark.
